nhanced Low-Clog Performance — for dirty
E
water applications
Faster Turnaround — up to 50% lead time
reduction and quick quotes helps to fit outage
schedules
Lower Installation Costs — up to 80% cost
reduction
Low Maintenance Costs — typical of an NC
FILM FILL
Low-Clog Performance:
• Splash fill allows for better low-clog performance
minimizing fill replacement frequency, downtime
costs and other expenses relative to film fill
• Heavy 235 galvanized or stainless steel structures
are stronger, lighter and more fire resistant
compared to pressure-treated wood towers
Faster Turnaround:
• Shorter quoting time than field erected towers
• Significantly reduced lead times compared to
field erected towers
• Improved ability to fit installation into an outage
schedule reducing downtime costs
Lower Installation Cost:
• Easy-fit maintenance options for quick installation
• Total installation time reduced by 80%
• Factory assembly provides one shipment with
minimal lay down area requirements
• Integral collection basin eliminates the cost
for a concrete basin
